Hello I'm a newbie with manipulation of Contact API
I would create an application that saved a references to chosen
contacts and create nex contacts.
So I first think of contact id but i have read that it was a bad idea
and the lookupkey was here for that ! So I try to play with lookupKey
and i'm facing some little problems...
First :
I choose a contact to saved, I did it by getting it's lookUpKey : no
problem.
I try to access later to contact with it's lookUpKey : no problem.
I go to contact native application, I change the first name of the
choosen contact.
I go in my application an try to access to choosen contact with saved
lookUpKey : problem, the contact lookUpKey has changed because I
change the first name...
Is there a way to have a unique access to a contact ? Or I was imagine
to register to modification done on my contact ? How could I solve my
problem ?
Second :
I created a contact with this code :
ContentValues values = new ContentValues();
Uri rawContactUri =
cr.insert(ContactsContract.RawContacts.CONTENT_URI, values);
long rawContactId = ContentUris.parseId(rawContactUri);
this.cur = this.cr.query(rawContactUri, new String[]
{ ContactsContract.RawContacts.CONTACT_ID }, null, null, null);
String id = null;
if (this.cur.moveToFirst()) {
id =
cur.getString(cur.getColumnIndex(ContactsContract.RawContacts.CONTACT_ID));
this.cur = this.cr.query(ContactsContract.Contacts.CONTENT_URI, null,
ContactsContract.Contacts._ID + " = ?", new String[] { id }, null);
if (this.cur.moveToFirst()) {
Log.i("ContactAPI5", "LookUpCreate : " +
cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY)));
} else {
Log.i("ContactAPI5", "no contact created");
}
}
And for these code, the result of lookUpKey is always an empty string.
Why do I have an empty string ?
Best regards
